Also another reason Katy and Rihanna did well, is because they did not promote like Gaga did yet were still close with her album sales. Gaga advertised everywhere, trains, subways, buildings, stores, Best Buy and her album sells didn't even double Katy's and Rihanna's album sales how sad. People though are getting bored of her costumes and waking up about her generic music. I laugh when people claim Gaga is an artist when all majority of her songs are about sex. A real artists music consist of their personal lives,politics, or anything important. An artist may even make a song about sex, BUT the majority of their songs will be about important things. And most importantly they will be themselves and won't try to be Pop/Mainstream nor will try to be famous. Gaga is NOT an artist.
